higher expression of STXBP5, GALP and LOC387646 indicated poor prognosis for a breast cancer patientincreased CTSLP8 and RPS10P20 and decreased HLA-K pseudogene expression indicates poor prognosis; regarding pseudogene–gene interaction, GPS2-GPS2P1 improved prognosis, but neither the gene nor pseudogene alone is prognostic of survivalmiR-3923 was predicted to target GPS2 using miRanda, PicTar, and TargetScan, implying modules of gene–pseudogene miRNAs that are potentially functionally related to patient survival. The gene discussed is GPS2P1; the disease is breast cancer.
